Actually it is true. Men's Health and Men's Fitness models use a very intense workout that mixes cardio and compound movements with very little rest in between sets, ie they will do a set of 8-12 squats, followed immediately with 8-12 pull ups...it produces HUGE amounts of lactic acid and strips the body fat because it releases masses of growth hormone, spurs lactic acid release, challenges the cardiovascular system to no end and punishes the central nervous system, which apparently simultaneously increases strength, causes hypertrophy and causes body fat to drop.
The premise for this trainign is you train in a way that forces GH to engorge and enter your muscle cells by stimulating lactic acid release, and create an afterburn effect that is far superior to aerobic exercise (because the damage you will do to your nervous system and the shock you will inflict on your muscles will create a large energy demand to repair them), similar to HIIT training, but with weights, eliminating the possibility of catabolism. By using the hardest compound exercises, you also stimulate testosterone surges.
I read about this style of training, termed "Meltdown", somewhere, it was written by Don Alessi, I think. Tried it once, had me puking all over the place and sweating like an idiot. Don't think I'll try it again anytime soon.
On the real though, always do your research before you say something is 'untrue'. Nothing in fitness and fitness nutrition is necessarily 'untrue', except for spot reduction, there are new discoveries every day, and besides, everyone's body is different....we all know much less than we think we do, which is why we're on this board to learn everyday.
Peace.
